The psychological benefits of music-evoked nostalgia

We provide a narrative review of the nascent literature on the psychological benefits of music-evoked nostalgia. Music is a prevalent and influential source of nostalgia. Music-evoked nostalgia confers approach-oriented psychological benefits in the social domain (by fostering social connectedness), self-oriented domain (by raising self-esteem, instilling a sense of youthfulness, elevating optimism, and enhancing inspiration), and existential domain (by strengthening meaning in life and augmenting self-continuity). Music-evoked nostalgia also confers psychological benefits indirectly. For example, it elevates optimisms by fostering sequentially social connectedness and self-esteem. Also, by fostering social connectedness, it enhances inspiration, strengthens meaning in life, and augments self-continuity. Furthermore, music-evoked nostalgia serves to buffer individuals against discomforting states, such as sadness. We conclude by discussing music-evoked nostalgia in people with dementia, contemplating the role of individual differences and context, considering the possibility that music-evoked nostalgia serves physiological functions, and asking whether familiarity with the music is necessary for the evocation of nostalgia and its ensuing benefits.
